RAILWAY-SWITCH;

SPECIFICATION forming part of Letters Patent No. 522,884, dated July10,1894. Application iiled January 8, 1894:- Serial No. 496,065. (Nomodel.)

To @ZZ whom it may concern.-

Be it known that I, WILLIAM C. DILLMAN, of Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedRailway-Switch, of which the follow- My invention relates toimprovements in railway switches and particularly to such switches asare adapted for use on street railways.

The object of my invention is to produce an extremely simple switch andswitch-working mechanism, which may be easily applied to an ordinaryrailway and to the usual swinging switch rail or point; which has itsparts arranged beneath the road-bed in such a manner that they cannotwell get out of order ori become clogged, and which may be operated froma moving car so as to throw the switch point in either direction.

To these ends my invention consists'of certions of parts, which will behereinafter described and claimed.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar figures of referenceindicatecorresponding parts in all the views.

`Figure 1 is a plan view of a railway provided with my improved switch.Fig. 2 isa longitudinal section on the line 2 2 of Fig. Fig. 3 is across section on the line 3+3 of Fig. 1; and Fig. Llisa similar section,showing a modified arrangement of the `shifting arms. a

The track has the usual rails l0, and at their junction with a siding11, is arranged the usual switch point 12 which swings on the customarygrooved face plate 13, this being perforated, as shown at 14, so thatdirt and dust may drop through into the chamber l5 below the road-bed,which chamber may vent it from filling up with water. Arranged in thechamber 15 is a lever 16 which extends substantially parallel with thetrack rails and is adapted to swing horizontally, it being fulcrumed ona suitable support, as shown at 17 in Fig. 1, and one end of it is bentupward, as shown at 18, and` is pivoted to aconnecting rod 19 which isconnected with the switch point`12, so that the swinging of the lever 1Gactuates the switch point. The other end of the lever 1G is, preferably,somewhat wider at the top than at the bottom, see Fig. 3, and

is clasped by rollers 2O on the ends of the bent arms 21 which arearranged on opposite sides ot' the lever 16 and are carried by avertically tilting lever 22 which is arranged transverselyin the chamber15 and is pivoted at the center on a supporting post 23.

The ends of the lever 22 are bent upward, as shown at 24, and terminateat the top in plates 25 which are adapted to lie iiush with the road-bedand to move vertically in slots 26 in the top of the chamber 15. Theseplates are adapted to be engaged by a depressible wheel or any otherlight object on the car, and when either plate is depressed it tilts thelever 22 and causes one ot' the rollers 2O to push against the lever 16,thus swinging the lever on its fulcrum and throwing the switch point 12to one side. It will be seen that whether the switch point is` opened orclosed will depend on which plate 25 is depressed.

Instead of having the arms 2l arranged as in Fig. 3, curved arms 27 maybe used, as shown in Fig. 4, each arm curving upward from the lever 22over the top of the leverlG and having, at its ends, a roller 2O whichis adapted to engage the lever 1G on the opposite side from the fastenedend of the arm 27, and it will be seen that this arrangement causes thelever 22, when tilted, to impart a movement to the lever 16 just thesame as that imparted to it by the tilting of the lever 22 when providedwith the arms 2l, but by the opposite arms 27. t In Fig. 4 the crossingof the arms 27 and their receiving between them the upper wider side oflever 16 render accidental displacement of the said leverimpossible.

It will beseen from the above description that the mechanism describedaords no obstruction whatever to the passage ot' vehicles over thetrack, and `that the switch may be worked by means of any kind of adepressible object on the car, such as a wheel or lever.

Having thus described my invention, I claim as new and desire to securebyLetters i Patenty A switch mechanism, comprising the switch point, alongitudinally extending lever 16 piv IOC oted between its ends andpivotally connected at one end with said point; the opposite shorter endof the lever having its opposite sides inclined downwardly and inwardly,a support beneath said inclined end, a transverse lever 22 pivotedcentrally to said support and provided with arms on its upper side atopposite sides of its pivot, said arms projecting toward the saidinclined sides and provided with anti-friction rollers in engagef menttherewith; one roller to run up one inoline to operate the lever whilethe other roller runs down the opposite lever to permit such operation,arms projecting up from the ends of the lever 22 and provided at theirupper ends withcontaet plates working in openings in the road bed,substantially as described.
